, .i ,1110. whom may concern.' y 1' Be it known that I, CHARLES E. DATH,a

citizen ofthe United States, residing at Chi- .cago\ in the countyofCook and State'of Illinois, have invented a certain new and usefulImprovement in Draft-Rigging Yokes,

' of which the following is a full, clear, conoise,` vand .exactdescriptionf, reference being `had to the accompanying` drawings,forming t' a part of this specification. AThis invention lrelates toimprovements In fdr'aft rigging yokes.

'n For many years railroads and railroad supply manufacturers have beendesirous of providing a yoke and'draw bar connection, 'wherein thelatter may be 'readily detached y Withoutgdropping the draft oear oryokeand .having 'the partsso arranged that the at` taching means aresuitable for use with any standard draw barwhether the same is providedwitha coupler key slot or not, and wherein slotting of the sills isavoided. As

' is well known, detachable draw bar and yoke 4`connections' are beingused more and-more f 'by :railroads and difficulty has beenenperiencedin providing a draw bar and vyoke connection which is attachable to oldtypes of draw bars, since it is found that many old draw bars nowinservice are not provided witlra coupler key slot. Furthermore,v manyin 4the' novel combinations of the 'parte and devices here; shown,described or claimed.`

i' l. l n` the dr., Jini-f forming a part-oi this specifiatioin' 1 is apartside eleva- "tion, part vertical section, of ayoke and draw l, har`showing my improvements in connection jtherewi- Fig. 2 ishorizontal,,longitudiy nal. sectie.w taken substantially on `the line2--'-2 of a front end elevation ofthe improved yoke. F 1g. e 1s a detailof the railroads object to havingvthe draft sili's Vslotted for thereception of a' coupler perspective ofthellocking block employed with myimprovements.` ,And Fig. 5 is a ver- -ticalysectional View olf a.portion of a draft structure illustrated in Figs. 1 to l, A designatesgenerally a cast steel yoke of tandem design having an upper arm 10,lower` arm 11, rear member 12, and integral hollow central thimble orpost 13. At its front end, the yoke A is provided with a substantiallyrectangular hollow hood or.head having an upper wall 14, side walls -15,andv a lower, vtransversely extending bridge or connecting piece 16.. Atits upper end, the hood or head is provided with a transverselyIextending front gib or shoulder 17 and a. rear transversely extendinggib or shoulder 18 adapted to engage the front and rear shoulders of thedraw bar butt 19. At its loWerend, the hood of the .yoke is providedwith anupstanding gib (ir-shoulder 20 against which the rear face of theydraw bar butt lengages under buff. To support the draw bar buttl inproper position and to lock it in' place, l have provided `a detachable'and removable looking block ingly formed groove or recess 23 inthe hoodof the yoke. At its front end, the lock block 21 is provided wit-h anupstanding gib or shoulder 24 arranged to engage'the lower frontshoulderiof the draw barbutt.' Said block 21 is also provided with a.depending ,flange 25 which lits against the inner face of the bridge 16and is adapted to be bolted 'thereto as by bolts 26-26. I also providean angle plate 27 arranged as most' clearly shown in Fig. l, said plate27 having its upper flange extended rearwardly andl seated within atransversely extending slot 28, formed in, the front lface of the block21, whereby the angle plate -27 assists inv supporting theblock 21 inposition.l y The hood of the yoke is also provided'with shoulders 29- 29on the innerfaces of the side walls thereof just abovejthe bridge 16,said shoulders having theirl rear facescurved to ,correspend withthecurved frontface SOo'f the gibor 'shoulder 24, yThe block 21 is. also`rounded at its rear end as indicated `at 31, in

order to facilitate insertion of the block 2l.,

l pivotal connectionwith the adjacent part of the yoke. When the block21 is removed,

the draw bar butt may then be lowered sufliciently for the uppershoulder thereof to clear the gib 17 whereupon thedraw bar may bevpulled out. The parts are assembled by steps the reverse of those abovedescribed, as will be understood.

In buff, the draw-bar butt will engage the lshoulders 18 land 20 andthereb force the yoke rearwardly to actuate t e tandem gears. In draft,lthe draw har butt will engage the gibs orshoulders 17 and 2-1 and inthis'connection, it will bednoted that the shoulder 24 is rigidly bracedby the inwardly extending shoulders 29, the block 21 as an'entire'tybeing also braced by engagement with the bridge 16 and flange 3 2.

In the yoke illustrated in Fi 5, the arrangement is the sameas thatiustrated in the other figures except that the gibs or shoulders 18 and20 of the yoke shown in Fig. 1 are omitted, so that upon buff or inwardmovement of the draw bar, the' latter- .will lengage directly the frontfollower of the gear and may slide inwardly independently of the yoke.

From the preceding description, 4it will be seen that the draw bar andyoke connection -`which I have provided `is adapted for all 'standardtypes of draw bars, the draw bar may be replaced or removed withoutdisturbing the gear or the yoke, no slotting of the sills is necessary,and all the parts are readily accessible from beneath the draft riggingeven though the draft sills may extend down below the lower partof theyoke.

Although I have herein shown and described what I now consider thepreferred.v

method of carrying outmy invention, the same is merely illustrative andI contemplate all such changes and 4modifications that come within thescopelof the claims appended hereto.
